Installing gstreamer libav plugin via rhythmbox.

Tried installing a gstreamer plugin ( gstreamer1.0-libav ) via rhythmbox ( "Install additional software required to use this format" button ). It opened gnome-software, which crashed with assertion failure after a couple of seconds.

commit d068f3a94fdd2ac30913be51f1ec7d8c4d5f81b3
Author: Richard Hughes <richard@hughsie.com>
Date:   Mon Oct 17 10:03:22 2016 +0100

    Fix an assert when a codec is not found
    
    When we can't find any results we now return an empty list rather than an error.
    Handle this in the various places that look for codecs to prevent a crash.
    
    Fixes https://bugzilla.gnome.org/show_bug.cgi?id=772996
